FERC issues permit for 150-MW pumped storage hydro project in Nevada

The Federal Energy Regulatory Commission on Oct. 29 granted a preliminary permit, good for three years, so Green Energy Storage Corp. can study the feasibility of a pumped storage hydro project in Nevada.

On April 3, Green Energy Storage filed and revised on May 14 and June 18 an application for a preliminary permit for the proposed Weed Heights Pumped Storage Project, to be located off-stream near the town of Yerington in Lyon County, Nevada. A license application would need to be filed if the company decides to pursue this project beyond the feasibility stage covered by this preliminary permit.

The proposed 150-MW closed loop pumped storage project would use the 775 feet of available head between a new upper reservoir and the former Anaconda open pit copper mine. The project would consist of: a new 35-foot-high upper dam with a total crest length of 8,000 feet, impounding an upper reservoir with a maximum storage of 2,600 acre-feet; a tunnel connecting the two reservoirs consisting of an 800-foot-long, 16-foot-diameter shaft; two 75-MW pump/turbines; a 2,700-foot-long, 16-foot-diameter draft tube, extending from the turbines to the lower reservoir; and a new 120-kV transmission line extending about seven miles from the project’s substation to an existing 120-kV transmission line owned by Sierra Pacific Power. The estimated annual average energy production would be 400 gigawatt hours.

The project contact listed in the application is: Charles Gresham, Green Energy Storage Corp., 14747 N 87th Ln, Peoria, AZ 85381, Phone: (602) 478-9161, E-mail: cg330@cox.net.
